Abstract

In this paper it is verified, from experimental results, that the Raman susceptibility asymmetry is found as a key factor to improve dynamic range in distributed anti-Stokes Raman thermometry sensor which operates in stimulated regime. Improvements are discussed from experimental results of the spatial evolution of the anti-Stokes and Stokes branches for different Raman anti-Stokes wavelengths.
